Correlation between Molar-Incisor Hypomineralization, Stress, and Family Functioning

Area of Science:

• Pediatric Dentistry
• Developmental Biology
• Psychoneuroimmunology

Background:

• Molar-incisor hypomineralization (MIH) is a common enamel defect affecting permanent molars and incisors.
• The etiology of MIH is multifactorial, with environmental factors playing a significant role.
• Understanding contributing factors like stress is crucial for prevention and management.

Purpose of the Study:

• To investigate the association between perceived stress in children and the presence of MIH.
• To explore the relationship between family functioning and MIH in children aged 7-9 years.
• To identify potential etiological factors for MIH development.

Main Methods:

• Retrospective study including 162 children (7-9 years) and their parents.
• Clinical examination for MIH diagnosis in children.
• Validated questionnaires assessing parental-reported stress and family functioning.
• Statistical analysis using Mann-Whitney U test and independent samples T-test.

Main Results:

• A significant positive correlation was found between higher stress scores and increased prevalence of MIH.
• Children experiencing higher levels of stress exhibited a greater occurrence of MIH.
• No significant direct correlation was identified between the quality of family functioning and MIH.

Conclusions:

• Stress is a significant correlating factor in the development of molar-incisor hypomineralization.
• Elevated stress levels may be a primary causal factor contributing to MIH.
• Further research is warranted to elucidate the precise mechanisms linking stress and MIH.
